Answer:

y=2, the equation of  a line which is perpendicular to the line 3x+5=0

A(-5/3,2)  the  foot of the perpendicular from B to the line

Step-by-step explanation:

d1 : 3x+5=0, so 3x=-5, x=-5/3

y=2, the equation of  a line which is perpendicular to the line 3x+5=0

A(-5/3,2)  the  foot of the perpendicular from B to the line

Andru [333]

Answer:

The value of n is the size of the sample, the number of customers selected.

The value of p is 0.48.

The value of q is 0.52.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

48% of consumers are comfortable having drones deliver their purchases.

This means that p = 0.48, q = 1 - p = 1 - 0.48 = 0.52

The value of n is the size of the sample, the number of customers selected.

A tree casts a shadow that is 24 feet in length. If the angle of elevation is 30 degrees, which of the following best represents
emmainna [20.7K]

Answer:

The answer is D) 13.9

Step-by-step explanation:

Since the angle of elevation is adjacent to the length of 24, than to find the height you have to use tangent. so you take your calculator in DEGREES mode and enter tan(30) which gives you =0.5773502692... than you would multiply by 24 which gives you the height =13.8564.....

Sorry if I wasn't specific enough, ask if you want more help. I am sure this is the right answer

ankoles [38]

Answer:

x=-1/4+i*sqrt(47)/4 and x=x=-1/4-i*sqrt(47)/4

Step-by-step explanation:

Using quadratic formula, x=(-1±sqrt(1-48))/4.

x=-1/4+i*sqrt(47)/4 and x=x=-1/4-i*sqrt(47)/4

Standard decision and percentage area
dimaraw [331]

Answer: standard deviation

is a measure of the amount of variation or dispersion of a set of values.[1] A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range.The standard deviation of a random variable, statistical population, data set, or probability distribution is the square root of its variance. It is algebraically simpler, though in practice less robust.The standard deviation is given by the formula: s means 'standard deviation'. S means 'the sum of'. Now, subtract the mean individually from each of the numbers given and square the result.

Step-by-step explanation :percentage area

i've never really heard of this but my sister just breifed me and this is what i could get

to calculate percentage area Find the percentage of a portion of an object by dividing the area of the portion by the area of the whole original object. Multiply the length times the width of the original piece to calculate its area in square inches, feet or centimeters

i hope it hrlps please mark me brainliest :)
